タイトル：Probing the spatial structure of a molecular attosecond electron wave packet using two-color laser pulses
発表者：Hiromichi Niikura, Department of Applied Physics,　Waseda University
abstract:
Using orthogonally polarized 800 nm and 400 nm laser pulses, we have generated high harmonics in ethane (C2H6). We observe that the intensity of each harmonic order modulates with the attosecond delay between the two laser fields. The modulation period of the low even harmonics is twice that of the period of modulation of the other harmonics. By comparing with theoretical calculation, we show that the double periodicity is a result of the electron wave packet motion in the valence shell of C2H6 on the attosecond time-scale. Our method is a general approach to measuring internal electron dynamics which does not require molecular alignment, making it applicable to more complex molecules than previous approaches.

タイトル：Stark shifts and multi-electron effects in tunneling ionization
発表者：Lars Bojer Madsen, Department of Physics and Astronomy, Aarhus University
abstract:
In this talk, I will describe two essential ingredients in strong-field tunneling ionization whose effect have very recently been observed in the photoelectron distribution in state-of-the-art molecular alignment/orientation [1] and attoclock [2] experiments: (i) the Stark shift and (ii) the field-induced polarization of the multi-electron system of the remaining ion.

Title: High-harmonic spectroscopy: From microscopic to macroscopic world.
Abstract:
I will report recent progress in theoretical understanding of high harmonic generation (HHG) from atoms and molecules,
including aligned molecules. New theoretical simulations, which combine single-atom/molecule response with the macroscopic
propagation of harmonic field in the medium, compare remarkably well with current experimental data. This provides foundation
for ultrafast dynamic imaging of chemical processes with few-cycle laser pulses

Title: "Laser-induced molecular dynamics with a classical model"

Abstract:
"A self-consistent model of a classical molecule is introduced.
Application of the model to the D3+ molecule exposed to a few-cycle,
intense laser pulse reproduces qualitatively experimentally measured
spectra, and yields insight into the laser-driven intramolecular
motion."
